Description

Adult males measure and adult females in

snout–vent length Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most c ...

. The snout is relatively long. The tympanum is larger in males than in females. The dorsolateral folds are thin. Skin on the dorsum is finely granular with scattered larger warts. The fingers have no webbing. The finger and toe tips bear expanded disks. Subarticular adhesive pads are present. Female frogs carry the eggs on their back. The eggs have direct development, hatching as froglets (i.e., there is no free-living larval stage).

Habitat and conservation

''Cryptobatrachus boulengeri'' are found on rocks within fast-flowing streams in primary and secondary montane forests at elevations of

above sea level Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The comb ...

. This species is abundant throughout its range, but it is threatened by habitat loss caused by agriculture (particularly coffee plantations), logging, and infrastructure development. Deforestation around streams is a particular threat. Additional potential threats are chytridiomycosis and pollution from agrochemicals. However, its range includes a number of protected areas, including the Sierra Nevada de Santa Marta and

Tayrona National Natural Park The Tayrona National Natural Park ( es, Parque Nacional Natural Tayrona) is a protected area in the Colombian northern Caribbean region and within the jurisdiction of the city of Santa Marta, from the city centre. The park presents a biodi ...
